The TMC389 is an energy efficient three phase stepper motor driver for high resolution microstepping applications. It integrates a low resonance three phase chopper for quiet motor operation. Its step and direction interface allows simple use. An SPI™ management interface allows for parameterization and diagnostics. The TMC389 directly drives 3 external N/P channel dual MOSFETs for motor currents up to 8A and up to 60V. Protection and diagnostic features further reduce system cost and increase reliability. TMC389²úÆ·ÁÁµã: Up to 171 microsteps (256 sine wave steps) using step/direction interface or 20 Bit SPI™interface High precision sensorless motor load measurement stallGuard2 Energy efficiency and coolness by automatic load dependant motor current regulation coolStep™s20 : Save up to 75% of energy! Internal microstep extrapolation allows 256 wave step smoothness with low frequency step input Dual edge step option allows half step frequency requirement, e.g. for opto-couplers Up to 8A Motor current using external N&P channel MOSFET pairs Synchronous rectification reduces transistor heating 9V to 60V operating voltage (peak) 3.3V or 5V interface QFN32 package for extremely small solution with superior thermal performance EMV optimized current controlled gate drivers ¨C up to 45mA gate current Overcurrent, short to GND and overtemperature protection and diagnostics integrated TMC389Ó¦ÓÃ: Precision three phase stepper motor drives Stage lighting Medical applications Optical applications Robotics Motor type 3 phase Stepper ![]() ͼ1.TMC389»ù±¾Ó¦Óÿòͼ ![]() ͼ2.TMC389·½¿òͼºÍÓ¦Óõç·ͼ ![]() ͼ2.TMC389²ÉÓÃÍâ½ÓÕ¤¼«Çý¶¯Æ÷µÄ¸ßѹ´óµçÁ÷¹¦Âʼ¶µç·ͼ ![]() ͼ2.TMC429 StepDir¿ØÖÆÆ÷ºÍSPI»¥Á¬µÄʾÀýͼ TMC389ÆÀ¹À°å The TMC389 evaluation board features a TMC389 with external power MOSFETs plus a microcontroller, which allows interfacing to a PC for visualization and control of all parameters. The motor can be operated via the step and direction interface, using either an external source, or using the integrated microcontroller as a step pulse generator. The TMC389-EVAL allows you to explore all functions of the TMC389. The evaluation board comes with a PC software which gives you access to every function of the driver. It comes along with a Step&Direction interface, a RS232 and a USB port. The TMC389-Eval is a complete "plug and play" solution, additionally only a motor, a PC and a power supply are required!
